Title: Constant charge time of defibrillation capacitor
Inventor: MENKEN JOHN
IPC: A61N1/37
Filed: 1993-11-18
Granted: 2000-01-25
Abstract: A capacitor charging circuit for charging a defibrillation capacitor in a constant period of time regardless of battery voltage by employing a controlled duty cycle charging technique. The defibrillation capacitor is charged in a piecemeal manner through a transistor and flyback transformer circuit. The gate of the transistor is driven by a constant frequency pulse train inverter drive signal in which voltage is conveyed to the capacitors during one-half of the full cycle of the pulse train.      The primary of the transformer is controlled by each pulse of the inverter drive signal so that the secondary of the transformer supplies current to the defibrillation capacitors during the off half cycle of the drive signal, the charge being built up in the defibrillation capacitors incrementally during the off half cycle of the inverter drive signal until the predetermined voltage is reached.

Patent CA-2115682-C (CA)
Inventor: KONO IKUO
IPC: E02D3/12
Filed: 1994-02-15
Granted: 1998-09-15
Abstract: An   apparatus    for   constructing   subterranean structures, soil-chemicals mixture or soil-agents mixture by using a multi-shaft auger machine to mix oil with a chemical hardener in situ.   As the auger shafts of the multi-shaft  auger  machine  penetrate  the  soil, spiral flights attached to the auger shaft above the initial auger  blades  assist  soil  in  passing  by  supporting structures located between adjacent auger shafts. The spiral flights both assist in raising the soil beyond the supporting structures and also prevent reagglomeration of the soil prior to passing by the supporting structures.          The spiral flights have a diameter less than that of the auger  blades  attached  to  the  shaft  below  the  spiral flights and have a connection ranging from 360 degrees to 720 degrees around the shaft.   The use of the spiral flights within this location results in a reduction in the amount  of energy needed  to auger a borehole,  thereby resulting in excess energy for a more homogeneous mixing of the chemical hardener in the soil through which the auger passes. In addition to the increase in efficiency because of the available energy, the spiral flights also directly increase the surface area of structures attached to  the  auger  shaft  thereby  increasing  the  mixing efficiency of the auger shaft as it passes through the borehole.  The increased efficiency and the prevention of reagglomeration  of soil are most beneficially observed in clay or clay-like soils.

Title: Sequential information integration service for integrating transfer of files or other data entities between a plurality of program modules and a storage in a computer
Inventor: NGUYEN HA T
IPC: G06F3/0481
Filed: 1994-05-20
Granted: 2000-03-14
Abstract: A number of program modules (32, 34, 36) are sequentially controlled by a procedural user interface (PUI) (38) and an operating system (40) to perform tasks. Transfer of files or other data entitles between the modules (32, 34, 36) and a storage (13) is seamlessly integrated by a sequential information integration service (SIIS) (50). For reading a file from the storage (13), the PUI (38) or the operating system (40) generates a read command including a filename designation which can include a pathname, complete filename or wildcard characters. The read command can also include one or more arguments such as a user or group access code and an error message to display if the required file is not found. In an automatic mode, the service (50) automatically selects the most recent file corresponding to the filename designation and arguments, or displays the error message if a file meeting these criteria is not found. In a manual mode, the read command includes a manual selection argument which controls the service (50) to display a list of files (64) corresponding to the filename designation and arguments in a dialog box or window (60) for manual selection. The read command can further include a pmmpt message (62) for display in the window (60) together with the list of files (64).

Filed: 1995-02-01
Granted: 2005-06-28
Abstract: An osteoarthritic knee brace is provided having flexible upper and lower arm members rotatably connected to each other by a rotary hinge assembly. A selectively inflatable or deflatable fluid-containing pad is positionable between the hinge assembly and a side of the knee joint. In operation, the brace is mounted on the leg with the pad engaging both the hinge assembly and the side of the knee joint, the hinge assembly aligned with the knee joint, and the upper and lower arm members aligned with the upper and lower legs, respectively. The upper and lower arm members are stressed away from the knee joint, thereby applying a restoring force to the knee joint across the hinge assembly and the pad that effectively treats the osteoarthritic knee joint. The restoring force is adjustable by selective inflation or deflation of the pad.

Title: Rail-based closed circuit t.v. surveillance system with automatic target acquisition
Inventor: GLATT TERRY LAURENCE
IPC: H04N7/18
Filed: 1995-05-18
Granted: 2005-10-04
Abstract: In a rail-based closed-circuit TV surveillance system, initialization is performed by positioning the surveillance camera at two different positions along the rail from which a target image is acquired. Camera direction parameters for each of the positions are stored. From the stored parameters there is calculated an optimum position for target acquisition. A normal surveillance routine is interrupted in response to an alarm signal. If the camera is within a range for viewing the target, target acquisition occurs immediately while the camera is moved toward the optimum position. If the camera is not within the range for viewing the target, the camera is moved toward the viewing range, while camera direction and focus are adjusted so that target acquisition occurs as soon as the camera reaches the viewing range. Camera direction and focus continue to be adjusted so that a target acquisition is maintained while the camera is moved within the viewing range toward the optimum position.

Abstract: A circulator section in a transceiver receives a transmit  signal  and  an  antenna  signal  and provides  them respectively to an antenna and to an electronic switch.  The electronic switch operates synchronously with the duplex mode of the transceiver to connect the antenna to a receiver when the transceiver is in receive mode, and to a matched load when it is in transmit mode. Since the signal path of any portion of the transmit signal reflected by a mismatched antenna is terminated  by  the  load,  power  which  otherwise  might  be reflected back to the transmitter and thereby damage it is instead absorbed by the matching load.

Abstract: A belt for use on a long nip press for dewatering a fibrous web includes a base assembled by spirally winding a prepared structure strip in a plurality of non-overlapping turns.  Successive turns are abutted against and joined to those previously wound by sewing or otherwise bonding along the continuous spiral seam thus formed.  The prepared structure strip may be a fabric strip woven from lengthwise and crosswise yarns, which may be monofilament yarns of a synthetic polymeric resin. The fabric strip may be of either a single- or multi-layer weave.  At least one side of the base, namely, that side which will be on the inside of the belt in its endless loop form, and which slides over the arcuate pressure shoe component of the long nip press during its operation,  is coated with a polymeric resin,  such as polyurethane, to render it impervious to liquids, and especially to the oil used to lubricate the surface of the arcuate pressure shoe.  The coating is ground and buffed to provide the belt with a smooth surface and a uniform thickness.
